Accidents happen. When that sudden realization hits days later that you need an email message that’s long gone, the Recover Deleted Items command might save your day. You can recover some deleted items, like messages, appointments, contacts, tasks, and notes, even after the Deleted Items folder is emptied or you’ve “hard deleted” an item by pressing Shift+Delete. This feature requires a Microsoft Exchange Server account and doesn’t work with POP3 or Internet Message Access Protocol (IMAP) accounts.
